LASTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 698,476, dated April29, 1902.

Application filed April 19,1901. Serial No. 56,574.. (No model.)

To all whom it may concern/.

Be it known that I, REINHOLD EDER, man ufacturer, a citizen of theKingdom of Prussia, and a resident of Griefswalderstrasse 13, Berlin, inthe Kingdom of Prussia, German Empire, have invented certain new anduseful Improvements in-Lasting-Machines, of which the following is aspecification.

The present invention relates to improvements in means for stretchingand fastening the upper-leather of boots and shoes on lasts.

In the annexed drawings one form of construction of the said device isrepresented as an example. T

Figure 1 is a side view thereof, and Fig. 2 a section on the line A A ofFig. 1. Figs. 3 and 4 represent one of the nippers in plan view andsection on line B B, respectively.

In a hollow standardl a freely-rotatable head 2 is mounted, to which twosupports 3 and 4 are fixed, diametrically opposed to each other. On thepivot 5 on the support 3 the carrier 6 of the last 7 moves in thevertical plane of the axis of the apparatus, and on the support 4 ismounted a spindle 8, adapted to be adjusted as regards height byrevolving it. The mushroom-shaped head of the said spindle serves as asupport for the point of the last 7. On each support 3 and 4 nippers Sand S, respectively, are arranged, which serve to stretch and hold theleather on the last. The particular arrangement and construction of thesaid nippers will be hereinafter described. Of these nippers S ishorizontally adjustable with regard to the last 7 by means ofahand-wheel 10. The other, S, which is to a slight extent movable on thehorizontal pivot 11, canbe raised and lowered by means of a hand-wheeland rack 51. The rod15 is vertically guided inthe head 2 by means of anarm 13, sliding in 1.

guides 12 and a stationary bridge 14. The said rod'15 is normallypressed upward by the spring 16, but can be drawn downward by means of atreadle-lever 17. At the upper end of rod 15 are two arms 18, actingunder spring action and in the manner of nippers. These 'drawthe leathertight and hold it in the manner shown in Fig. 2. To facilitate theturning of the upper part into the most convenient position for working,a swiveljoint 19 is provided in the bar 15.

The nippers effecting the stretching and holding of the leather consistof two suitablyshaped levers 21, oscillating on a common fulcrum 20, thefront ends of the said levers being suitably hollowed out. The nippersare opened and closed by turning a disk 22, having on its upper sideeccentrically-placed pivots 23, which act upon the rear ends of thelevers 21 by means of connecting-rods 24.

In order to draw the leather very tight, the jaws of the nippers are notonly closed, but the latter are also advanced in the direction of thelongitudinal axis of the last. For this purpose the pivot 20 revolves ina sliding block moving in a groove 26 in the plate 27, covering thenippers, At the end of the said sliding block 25 is a pin 28, whichenters a slot 29 in the disk 22, the said slot being inclined at anangle of about forty-five degrees to the longitudinal axis of themachine. 011 disk 22 being revolved by means of a key placed upon thesquared end of its pivot the nippers are closed by means of thearrangement described, and the leather is drawn laterally tightly overthe last. At the same time the upper leather at the toe and heel of thelast is drawn tight by the displacement of the nippers themselves ontheir support.

What I claim is- In a lasting-machine, the combination with thelast-holderand the nipper-support adja cent thereto, of ahorizontally-disposed slidin g plate supported upon said nipper-support,a pair of horizontally-disposed nipper-jaws pivoted to said slidingplate, a cam-disk located beneath the rear ends of said jaws, acam-groove in said disk, links connecting said disk with the ends ofsaid nippers, and a pin carried by the plate engaging the cam groove inthe disk, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

' REINHOLD EDER.
